This paper is a survey of recent academic developments in the literature on green bonds, which have become an important financial instrument in socially responsible investment. This study provides a review of papers that study the market pricing of green bonds, the economic and environmental effects of green bond financing, as well as legal and institutional issues in the green bond market. The literature on market pricing focuses mainly on the existence of greenium, which represents the extent to which green bonds carry a price premium over otherwise identical non-green counterparts. The literature on the economic and environmental effects mainly concerns stock market reaction to green bond issuance and associated economic value implications to other stakeholders, as well as investment in green projects. This paper discusses current issues in the green-bond market and avenues for future research.

The study aims to consolidate knowledge, explore current dynamics, understand knowledge progression, identify primary research streams, present content analysis and provide future research directions for green bonds research.

The authors reviewed 150 high-quality Scopus-indexed articles on green bonds in two stages. First, they use bibliometric analysis to understand the field's most relevant articles, authors, institutions and journals. Second, they analysed 49 curated articles to identify and analyse primary research streams and offer research directions.

The authors report the most influential articles, authors, journals and clusters based on article co-citation networks. They identify five green bond research streams: issuance, greenium and its drivers, connectedness, drivers and barriers, and sustainable development.

Using different databases, tools, sample periods or article screening criteria may yield different results. The study's findings are robust to document selection or analytical tools.

The study helps researchers, practitioners, regulators, policymakers, issuers and investors understand green bond issuance, pricing and connectedness research.

This unique study sheds light on publication trends, the most influential articles, authors, journals and the conceptual and intellectual structure of the field. It identifies and elaborates primary research streams, succinctly summarizes the most influential articles and offers future research directions.

The present study examines the rationale behind the increased global presence of corporate green bonds as a green financing tool to facilitate sustainable practices and eco-friendly investing. The authors investigate the intriguing question of whether the companies that issue green bonds are valued more by investors or not, and further extend our analysis by exploring whether the green image of companies helps to minimize the value erosion during a crisis and enhance the resilience of the stocks?

To examine the association between environmental commitments and firm value, the authors use the COVID-19 crisis as an exogenous shock and create a perfect natural setting to eliminate the endogeneity bias from our estimations. Moreover, the authors use propensity score matching to choose a one-to-one match of green bond firms with a larger pool of brown bond firms and eliminate the “size effect” arising out of the disproportionate sample size of green and brown bond firms.

The results of the study indicate that green bond firms are valued more by investors compared to brown bonds firms. Hence, green bond issuance acts as a strong signal of a firm's environmental commitment and it is well recognized by the investors. One of the possible reasons for a higher value of green bond firms may be due to their ability to arrest value erosion during environmental shocks. The authors could not find any difference in the resilience of green and brown bond firms.

The study contributes to the growing literature in the area of impact investing, specifically on exponentially growing innovative instrument green bond. Our study integrates two areas of research, i.e. corporate finance and impact investing by examining the impact of green bond issuance on firm value and stock market returns. The results would help environmentally sensitive investors to devise their investment portfolios more efficiently.

This paper aims to examine the Canadian financial sector’s reaction to opportunities and risks created by the green bond market in a low-carbon and climate-resilient (LCR) economy.

The authors used a concurrent mixed methodological approach that undertakes an online survey and semistructured interviews with critical green bond market stakeholders.

The most significant market driver in Canada is the reputational benefit for stakeholders, i.e. its ability to meet the high demand for sustainable finance and the marketing potential of its green credentials. The major market barriers are transactional costs, i.e. additional tracking required for reporting purposes, lack of market liquidity and identification of environmental impact or additionality. Canadian green bonds are also more likely to be evaluated on their green impact than their global market peers.

Limitations of this study include its focus on Canada, which may exclude or not apply to drivers and barriers in other green bond markets.

The paper helps create an accounting-based conceptual framework for key motivations and barriers that affect financial decision-making regarding green bonds.

The authors identify economic and policy-related barriers and drivers for green bonds, addressing the financing gap for the LCR economy.

To the best of the authors’ knowledge, this study is the first to identify and compare Canadian green bond market drivers and barriers and to examine relevant stakeholder- and policy-related approaches that can be targeted to scale this market effectively.

Green sukuk (GS) is an emerging financial tool that has gained momentum in recent years owing to increased attention being given to Islamic finance, socially responsible investing (SRI) and sustainability agendas. Yet, GS studies are fragmented, dispersed and lack comprehensive reviews. As a response to this gap in academia, this paper aims to synthesize the knowledge on GS into thematic clusters, providing a more comprehensive understanding of the subject and offering guidelines for future research.

This study implemented a systematic literature review approach to analyse studies on GS that were published prior to and including June 2023. The PRISMA 2020 protocol was used in the sample selection process. A total of 62 peer-reviewed journal articles from six databases were identified and categorized into various themes.

The results suggest that previous research has predominantly focused on the areas of GS advantages, drivers, market development and potential sectors, along with challenges and recommendations to improve the market. However, it was found that some other aspects, including GS pricing, performance and purchasing intention, require further research attention. The analysis also indicated that the use of theories in the GS context was limited, with only five theories employed in just four out of the 62 articles examined. Moreover, this paper’s findings revealed that the studies employing quantitative and empirical analysis methods were limited to four articles. Geographically, most of the studies were conducted in Indonesia and Malaysia, while other countries with high-potential markets (e.g. GCC) had limited GS practices and studies.

The results of this study have several practical implications. For investors, a review of GS will provide greater insight into the understanding of the GS market, helping them make better investment decisions. For policymakers, this paper empowers them with the knowledge to make informed decisions regarding GS markets by highlighting key recommendations identified in the literature. Finally, the proposed guidelines can be used in future research.

While Green Bonds have received significant attention, there is a dearth of research on GS and those that exist are fragmented. A systematic literature review is necessary to identify knowledge gaps for future research.

Sustainable investments (SI) represent a promising class of investments, combining financial returns with mitigating environmental challenges, achieving SDG goals and creating a positive business impact. An enhanced global focus on climate change developments in the backdrop of COP26 and COP27, raised the need for comprehensive literature mapping, to understand the emerging themes and future research arenas in this field.

The authors apply a quali–quantitative approach of bibliometric methods coupled with content analysis, to review 1,022 articles obtained from the Web of Science (WoS) database for 1991–2023.

The results identify the leading authors and their collaborations, impactful journals and pioneering articles in sustainable investment literature. The authors also indicate seven major themes of SI to be financial performance; fiduciary duty; CSR; construction of ESG-based portfolios; sustainability assessment tools and mechanisms; investor behavior; and impact investing. Further, content analysis of literature from 2020 to 2023 highlights emerging research issues to be SDG financing via green bonds and social impact bonds; investor impact creation via shareholder engagement and field building strategies; and governance related determinants of firm-level sustainable investments. Finally, the authors discuss the research gaps across these themes and identify future research questions.

This paper crystallizes research themes in sustainable investment literature using a vast coverage of globally conducted studies published in reputed journals till date. The findings of this study coupled with future research questions provide a well-grounded foundation for new researchers to further explore the emerging dimensions of this field.

This study aims to examine the effects of green financing through pollution control bonds (PCBs) on environmental performance.

This study is based on a panel of 189 US energy utility firms observed over the period, 2011–2021 ; this study applies Generalized Method of Moments regressions.

This study found that PCBs positively affect environmental performance (aggregate measure, greenhouse emissions, waste landfill, waste incineration and waste recycling). These findings remain robust when this study considers alternative measures of PCBs and environmental performance, the quantile regression method and some firms’ attributes such as financial performance and firm age.

The results indicate that US energy utility firms have to adopt more PCBs. This study helps researchers, practitioners, shareholders, bondholders, equity analysts and local authorities such as the California Pollution Control Financing Authority, municipalities and investors understand PCBs issuance, usefulness and relevance.

To the best of the authors’ knowledge, this study is the first to explore the effectiveness of PCBs in reducing pollution.

This paper aims to providea comprehensive review of the concepts and definitions of green finance, and the importance of “green” impact investments today. The core challenge in combating climate change is reducing and controlling greenhouse gas emissions; therefore, this study explores the solutions green finance provides emphasizing their impact on the environment and firms' financial performance. With increasing attention to the concept of green finance, multiple forms of green financial tools have come to fruition; the most prominent are green bonds.

This paper compiles a comprehensive green bond dataset, presenting a statistical study of the evolution of the green bonds market from its first appearance in 2006 until 2021.

The green bond market has seen massive growth over the years reaching $1651.92bn as of 2021. Findings show that green bonds are working towards shifting from high carbon-emitting energy to renewable energy, which is vital to economic development and growth. In congruence, green bonds are aligned with the United Nation's sustainable development goals (SDGs) amounting to $550bn for 2020, with the five most covered SDGs amounting to over 60%.

With growing worldwide concern for global warming, green finance became the fuel that pushes the world to act in combating and mitigating climate change. Coupled with adopting the Paris Agreement and the SDGs, Green finance became a vital tool in creating a pathway to sustainable development, as it connects the financial world with environmental and societal benefits.

The main objective of the study was to compare Business Responsibility and Sustainability Report (BRSR) norms with Global Reporting Initiative (GRI) standards, so as to establish whether BRSR norms match the global standards and best practices or not. Additionally, an effort was made to ascertain and highlight areas where BRSR norms are more comprehensive, just match, or require further refinement to be at par with the GRI standards. The study highlights the similarities and dissimilarities between the internationally accepted GRI standards and the BRSR framework; thereby suggesting areas of improvement for the BRSR framework.

Scrutinised all the 36 standards of the Global reporting initiative and BRSR format and guidelines of the Securities Exchange Board of India. The Content Analysis Technique was used to ascertain the percentages of similarities between the two frameworks.

The content analysis found that there are 52.30% similarities between BRSR norms and GRI standards. Further, this study shows the factors that led to the dissimilarities between BRSR and GRI standards. This study found 18 areas where BRSR is more informative than GRI, and 7 areas where BRSR could be further refined.

This study contributes to research in the sustainability reporting framework to be adopted by Indian listed companies. There are a few Indian listed companies who are already reporting as per the GRI framework and might perceive the BRSR as a separate reporting altogether. But as found in this study, more than half of the BRSR framework is similar to the GRI framework; thus, half the work is almost done. As such this study helps Indian firms in developing an understanding of the BRSR and puts in perspective its standing among global sustainability reporting standards. This study shall help institutional investors, rating agencies, and external assurers to better visualize an Indian entity, by referring to its Business Responsibility and Sustainability Reporting.

This paper aims to quantify the impact of environmental contamination on farmland valuation. It applies data fusion and hedonic pricing approaches to quantify the contribution of nitrogen and phosphorus loading on farmland sales transactions. It further suggests approaches to improve internalization of environmental cost in valuation approaches using shadow pricing. The work informs the field of environmental, social and governance (ESG) investing by fusing environmental data with financial transactions.

This paper is an empirical study implementing hedonic pricing of farmland in the Lake Huron major drainage area. Data sources and fusion were derived from AcreValue, the United States Department of Agriculture's Gridded Soil Survey Geographic database (gSSURGO) and the United States Geological Survey's Spatially Referenced Regression on Watershed Attributes database (SPARROW).

The results suggest that environmental contamination has statistically significant positive determination power on farmland prices such that prices increase with contamination. Conventional metrics such as percentage of cultivated land in the parcel, root zone depth, whether the parcel is designated by the Natural Resource Conservation Service as prime farmland, and the size of the farmland parcel contribution to farmland value as well. The results indicate that environmental impacts are not accurately accounted for in farmland transactions.

This paper points to inaccurate valuation of environmental contamination in farmland value. While geocoding allowed for positioning of farmland sales transactions relative to modeled areas of contaminant loading in the Lake Huron drainage area, the interpretation indicates that value is driven by cultivation. Hence, generalization to other areas needs a cautious approach. Empirical testing across locations and drainage areas with diverse farmland features will serve to verify the modeled data used in this study.

The lack of integration of externalities in land valuation has implications on lending and disclosure practices, as financial service providers increasingly seek to account for ESG risk on their loan books and broader investment portfolios. The impact of farmland accounting practices for contamination such as shadow pricing may impact land valuation based on future cash flows, and may serve to inform sustainability-linked lending practices to farm operations.

This is the first paper to fuse data from AcreValue, gSSURGO and SPARROW to discover the explanatory power of nutrient contamination in farmland value in the Lake Huron major drainage area.
